VSPARS for Rig - Bend, sag and twist

An enhanced rig tuning tool is also available within the VSPARS suite. Using the VSPARS Mainsail cameras the VSPARS software tracks the mast position in Real-Time and compares the current position to a known dock setting.
This results in a very high accuracy (<5mm resolution at 30m) plot of mast bend, sag and twist over a range of heights.

This means unequal stretch of rigging elements and dynamic behaviour can be accounted for whilst tuning your rig.
